SPEGEFLGATION forming part of Letters :Patent No. 675,529, dated June 4,1901.

Application tiled September 22, 1900. Serial No. 30,788. (No model.)

To @ZZ whom, 2325 may concern.-

Be it known that I, PHILIP SEIPEL, a citizen of the United States,residing at Watertown, in the county of Jefferson and State of New York,have invented a new and useful Printers Chase, of which the following isa specification.

This invention relates to printers chases; and it has for its object toprovide a construcro tion wherein the chase is composed of a numberofseparable parts which maybe variously connected to form chases ofdifferent sizes and forms, and wherein the parts may be readilyassembled and disassembled, and when assembled will be held securely inposition.

Further objects and advantages of the invention are evident from thefollowing description.

In the drawings forming a portion of this 2o specification, and in whichlike numerals of reference indicate similar parts in both views, Figure1 is a horizontal sectional view through the complete chase and showingthe means for holding the parts in their proper positions. Fig. 2 is aplan View showing the chase adjusted to a smaller size.

Referring now to the drawings, the present chase comprises a pluralityof sticks 5 and 6, of which the sticks 5 are shown as outside sticks andthe sticks 6 as inside sticks, although they are the same in everyrespect. Each of the sticks 5 and G has a central perforation 7, formedlongitudinally thereof, and, furthermore, each of said sticks has adovetail lug S at one end and a dovetail socket 9 at its opposite end.

Cooperating with the sticks 5 and 6 are corner-pieces 10 in the form ofright angles, one end of each corner-piece having a dovetail 4o lug 11,while the opposite end has a dovetail recess 12, the lugs and recessesof the sticks being adapted for engagement with the lugs and recesses ofthe corner-angles. Thus when it is desired to form a square chase of agiven size four of the sticks may be engaged with four of thecorner-pieces to form the chase. Each corner-piece has one perforationformed longitudinally through one leg thereof for alinement with theperforation through the 5o engaged stick, while the second leg of thecorner-piece has a recess in its outer end for alinement with thelongitudinal perforation of the stick that is engaged therewith. Thuswhen the four sticks and the four cornerpieces are engaged screws 13 maybe passed 55 through the alining perforations and recesses of thecoruer-pieces and sticks and into the recesses of the corner-pieceswhich register therewith, said recesses being threaded to hold thescrews in place, and by this means lateral 6o displacement of the partsofthe structure will be prevented.

In addition to the sticks and corner-pieces there are provided Tconnections 14, the ends of the heads of which are provided one with adovetail lug l5 and the other with a dovetail recess 16, while the stemsthereof are all provided with dovetail recesses 17. These T connectionsare provided with perforations 18, formed longitudinally through theirheads 7D and additional perforations 20, formed longitudinally throughthe stems and. passing transversely through the heads, the perforationsthus intersecting. The T connections are used when it is desired to forma chase for printing a number of folios, and in this case if four foliosare to be printed the four corner-pieces have each two sticks 5 engagedtherewith, the outer ends of these sticks being engaged with the headsof the T connec- 8o tions. Long screws 21 are then passed through thesticks7 the head of the T connection, and one leg of the corner-'pieceat each side of the chase and into the recess of the leg of the 0ppositecorner-piece, so that the outer frame of the chase is held firmlytogether. With the stems of the T connections are engaged sticks 6, andthe inner ends thereof which are recessed receive the dovetail lugs 22at the ends of a central cross-piece 23, the legs of 9o which areprovided with recesses.

The entire framework is put together before any of the locking screws orrods are put in place, and before placing the screws 21 v short rods 24are engaged with the perforaf- 95 tions, which aline in the sticks G andthe stems of the T connections and the recesses in the centralcross-piece. The screws 2l are then put in place and act to hold therods against displacement.

If the four-folio chase is to be changed to a two-folio chase, the fourcorner-pieces may be' IOO used With two T connections and the propernumber of sticks 5 and 6 to form the chase, as shown in Fig. 2 of thedrawings.

With this construction it will be seen that there is provided aconstruction of chase that may be readily adapted to use under variousconditions and it Will of course be understood that in practice variousmodifications of the specific construction shown may be made and thatany suitable materials and proportions may be used for the various partsWithout departing from the spirit of the invention.

What is claimed is- 1. A sectional chase comprising a frame includingmembers separably connected, crosspieces separably connected With theframe and with each other, means for holding the members of the frame incooperative relation, and means for holding the cross members inposition, the first-named holding means being disposed to hold thesecond-named holding means in position.

2. A sectional chase comprising a frame including separable membershaving longitudinal perforations therethrough, bolts engaged with themembers for holding them in cooperative relation, vcross-piecesseparably connected with each other and with the sides of the frame,said cross-pieces having longitudinal perforations and the frame havingperforations alining with the perforations of the cross-pieces andcommunicating with the longitudinal perforations of the sides of the 3.A sectional chase comprising members 4o having sockets and lugs thesockets and lugs of different members being adapted for interchangeableengagement by lateral movement of the members, said members having alsorecesses and perforations formed longitudinally thereof, and rodsengaged With the alining recesses and perforations to hold the membersagainst lateral movement With respect to each other to disconnect them.

4. A chase comprising a central cross-piece having recesses in its ends,angular cornerpieces, each havinga perforation formed longitudinallythrough one leg and a recess formed in the end of the second leg, Tconnections each having perforations formed longitudinally through itshead and stem, sticks having y longitudinal perforations therethrough,said members having dovetail connections, and rods engaged with thealining perforations and recesses to hold the dovetail connectionsagainst displacement.

In testimony that I claim the foregoing as my own I have hereto afiixedmy signature in the presence of two witnesses.
